In order to achieve the right current demands when designing a power-system,the author made a comparing study and practice among several linear current expansion circuits and got some useful circuits from them which are divided voltage by resistance and transistor in order to expand current.The effects of the current expansion circuits are obvious,and they have a simple structure,and cost low.Specially,these circuits are very useful to some occasions that the conversion efficiency of power is not very high.
